At 5:15 p.m. on September 25, 2004, nearly 6,000 men, women, and children, all wearing red T-shirts, gathered in a field in the Arche de la Nature park near Le Mans to be photographed for a postcard. The “1er décembre Sarthe” collective, which coordinated the event, donates the funds raised to the Kénédougou Solidarité organization in Mali, which works toward the prevention of AIDS and provides care for AIDS sufferers. Today sub-Saharan Africa remains the principal venue for the epidemic; in 2007, it accounted for 72 percent of AIDS-related deaths and 67 percent of the global population infected. Throughout the world, many organizations have been founded to provide support to the sick. In six years, the number of people on antiretroviral drugs in developing countries grew tenfold, to reach 3 million people in late 2007. Since the beginning of the 1980s, HIV—the virus that causes AIDS—has killed more than 25 million people. In 2007 alone, 2.1 million people died of AIDS. More than 33 million people were living with AIDS in late 2007, including 2 million children under the age of fifteen. Though the annual number of new HIV infections among children around the world has dropped in the past few years, 370,000 children were believed to have been infected in 2007.
